摘要:
本文从RFID技术在实际应用中经常出现多标签并存的特点出发,设计实现了一款多标签共存模型来测试多标签共存时的标签响应率分布情况,分析弱信号点产生原因。统计分析由该平台获取的测试数据,总结实验规律。通过测试不同间距标签的读取率分布得出结论,多标签响应率随标签间距的减小而降低,即标签密集排布时弱信号点较多。该实验结论对UHF标签在堆叠放置等密集排布的场景下合理摆放间隔的设置有指导意义。

Abstract:
This paper is based on RFID common applications. In this paper, a multiple measurement model is designed for responding rate test. According to this model, weak points in multiple tags can be analyzed. From the data measured by this platform, general conclusion can be made. According to data analysis based on different intervals between tags, we can conclude that with the intervals shrinking the responding rate drops quickly. That means there are more weak points when the interval is small. The conclusion is useful in multiple UHF RFID laying in a great quantity.
